This patch cleans up the behavior of scsi_host_lookup(). The original implementation attempted to use the dual role of either returning a pointer value, or a negative error code. User's needed to use IS_ERR() to check the result. Additionally, the IS_ERR() macro never checks for when a NULL pointer was returned, so a NULL pointer actually passes with a success case. Note: scsi_host_get(), used by scsi_host_lookup(), can return a NULL pointer. Talk about a mudhole for the unitiated to step into.... This patch converts scsi_host_lookup() to return either NULL or a valid pointer. The consumers were updated for the change.
